All Iron Ventures

All Iron Ventures, rebranded as Acurio Ventures in September 2024, is a Bilbao, Spain-based venture firm founded in 2017 by Ander Michelena and Jon Uriarte, who previously co-founded Ticketbis and sold it to eBay in 2016 for $165 million. With approximately €300 million in assets under management across three funds — Fund I (€66 million), a €30 million fund of funds, and Fund III (€150 million, closed 2024) — the firm has backed more than 90 startups across Europe and the United States. The 12-person team operates from offices in Bilbao, Madrid, Barcelona, and London. Partners Diego Recondo, Hugo Mardomingo, and Kate Cornell complement the founding duo. All Iron leads rounds at seed and Series A stages, deploying $500,000 to $10 million per investment, and focuses on consumer and enterprise technology including marketplaces, SaaS, e-commerce, edtech, adtech, HR technology, and mobility. The portfolio carries an impressive track record: 4 unicorns and 8 acquisitions among 90 or more companies. Notable investments include Seedtag, Jobandtalent (unicorn), Lingokids, Preply, Refurbed, Lookiero, Lime, and Zum. The founding partners bring a distinct perspective as entrepreneurs-turned-investors — having scaled Ticketbis across multiple markets before a major exit, they understand the realities of building globally competitive businesses from Europe. This operator credibility shapes the firm's hands-on approach to working with founders on strategy, market expansion, and team development, and underpins a portfolio construction philosophy that favours conviction bets on founders reshaping large markets through technology.
